Japanese teen 'didn't like' mother so chopped her up: Reports

TOKYO (AFP) - A Japanese teenager who allegedly killed his mother and chopped her body into pieces has told police he simply did not like her, and wanted to know more about dissection, reports have said.

The 19-year-old allegedly dismembered his mother's body in the bathroom, cutting her into at least 15 pieces using kitchen knives, the Sankei daily said on Saturday, citing unnamed police sources.

The teenager, who lived with his mother in a small apartment near Tokyo, then kept the body parts in the bathtub, which he filled with water, before starting to dump it piece by piece in plastic bags, the report said.

He told police he "didn't like her" and she was an "ordinary person", the Sankei reported, quoting an unnamed investigator.
